Chemical Burns. A chemical burn is a type of burn that is caused by exposure to a harmful substance, such as a strong acid or base. Chemical burns differ slightly from other types of burns as they need no heat source to cause corrosion to the skin or tissues. Certain chemicals can also penetrate into tissue without obvious damage to the skin.
